Patented Nov. 1, 1932 UNITED STATES PATENT orrlcs ADOLF BAUMANN AND CARL I. HOBLACHEB, OF ST. LOUIS, MISSOURI, ASBIGNOBB, BY MEBNE ASSIGNMENTS, TO THE AMERICAN EXCHANGE NATIONAL BANK ST- LOUIS, A BANKING CORPORATION CALCULATING MACHINE Application, filed April 11,

This invention relates to calculating machines and more particularly to machines adapted to perform the operations of multiplication.

One of the objects of this invention is to provide a machine in which the calculating operations are carried out in such a manner that the partial products are segregated and accumulated in order to indicate or record the final product.

Another object is to provide a machine in which the operations are performed in a simple and effective manner and by positive, simple and eflicient mechanism.

Another object is to'provide a machine in which the various resultin artial product correspondin to the mu tiplier are set up and those partlal products selected which correspond to the multiplicand, these selected partial products being then segregated and accumulated in order to set up the final product.

Another object is to ing machine in which rovide a multiplyt e multiplier is selectively retained in the machine, after the machine is cleared, in order to repeat the multiplier for various multiplicands.

Another object is to provide a multiplying machine in which the key setting may be selectively cleared, either partially or collectively.

Another object is to improve the machine as to details in order to improve its operation and simplify its construction.

Further objects will appear from the detail description taken in connection with the accompanying drawings in which:
